As I understand it, vouch works on dead submissions and comments: it doesn't negate or offset flags.
Contacting the mods (use the contact link in the footer) and asking them to review can be effective.

Is there anything that offsets a flag? Does a single flag click create the flag label, or does it take several clicks?
It seems unfair that a single person could trigger an unremovable flag label.
